Mouth ulcers concerns

Mouth ulcers are painful sores that appear in the mouth, usually on the soft tissue - cheeks, lips or tongue. They can be white, red, yellow or grey in colour and swollen.

Although they're uncomfortable, mouth ulcers are usually harmless and clear up by themselves within a week or two.

In many cases, the reason for mouth ulcers is unclear, but triggers are thought to include:

  • Accidentally biting the inside of your cheek or a sharp tooth
  • Poorly fitting dentures
  • Hard food
  • A defective filling
  • Stress and anxiety
  • Hormonal changes – some women develop mouth ulcers during their monthly period
  • Eating certain foods – such as chocolate, spicy foods, coffee, peanuts, almonds, strawberries, cheese, tomatoes and wheat flour
  • Toothpaste containing sodium lauryl sulphate
  • Stopping smoking – when you first stop smoking, you may develop mouth ulcers
  • Viral infections – including the cold sore virus, chickenpox, and hand, foot and mouth disease
  • Medical conditions - including vitamin B12 or iron deficiency, Crohn's disease, coeliac disease, reactive arthritis, HIV, lupus, Behçet’s disease
  • Certain medications or medical treatments may also cause mouth ulcers

It's usually safe to treat mouth ulcers at home to help reduce swelling and ease any discomfort.

Self care

Tips for easing discomfort and aid healin…

  • Antimicrobial mouthwash or protective paste, available from your pharmacist
  • Use a soft toothbrush to brush your teeth
  • Use a toothpaste that doesn’t contain sodium lauryl sulphate, as this may be irritating
  • Avoid hard, spicy, salty, acidic or hot food and drink until the ulcer heals
  • Use a straw to drink cool drinks
  • Avoid things that may be triggering your mouth ulcers

Mouth ulcers can sometimes be a possible symptom of a more serious problem such as infection or mouth cancer. It's therefore essential that you contact [practice name] as soon as possible if you notice:

  • your mouth ulcer has lasted three or more weeks
  • you keep getting mouth ulcers
  • your mouth ulcer becomes more painful or red

Friendly professional service as always.

If I was highly satisfied, and all of my answers confirm this, why do I need to add further comment. I had an emergency consultation which was highly satisfactory with a number of treatment options. What more could I add? Stupid added survey question!

25th July 2026

Things explained very well. Can't fault the system or the staff.

24th July 2026

I was fully consulted and listen too - plus treatments option were fully explained by a caring and pleasant team.

Mr Amit Gadafi is simply the best.

My visit had been planned from a previous apointment with Marc, so I knew exactly what treatment I was there for, which Marc carried out painlessly and efficiently

I always receive excellent service at Mortiboys but I am very disappointed that the clinic has taken the decision not to keep the 2 different hygiene treatments at different prices. I am not aware of receiving any communication from yourselves to pre-warn me that the cost of the hygiene treatment would be the same whether I had it done in the previous way or using the new treatment procedure. I was shocked to learn when I was at the clinic for my appointment that this was the case. I also think it's unfair to leave that communication to the hygienist. This should have been communicated by the practice ahead of time.That's my only gripe. I appreciate the cost of running a business and providing services has increased considerably lately and those costs need to be passed on to continue to provide this service but it really should have been made clear ahead of time

All very efficient, friendly courteous service as usual. Feel in competent hands with dentist and all.

27th June 2026

Marc will always explore to find the simplest way to complete a treatment, as opposed to the most expensive.

One of the things I like the most about Mortiboys is that it doesn't feel or smell like a dentists, so it put's me at ease immediately.Staff are always very friendly and the patient care from Marc is exemplary. He has a way of explaining things without terrifying you.
